3. Do a complete inventory of every part, nut and bolt. Yes it takes time, but it also allows you to noti- fy SteppIR if anything is missing and allow time to get it to you before you start assembly of the antenna.
OK - - - NOW WHAT? (continued) (Sage advice from Jim Streible, K4DLI—SteppIR Technical Support Guru) 5. Take the controller and power supply out of their wrappings and connect them. The controller does not have to be connected to the antenna in order to familiarize yourself with it. In fact, it is best to get familiar with the controller when it is not connected to the antenna.

SteppIR offers saddle sizes in 1-3/4”, 2”, 2-1/4”, 2- 1/2” and 3”. Since the vast majority of installations of the DB42 will be utilizing the standard 2 inch saddles, that is the verbiage used in the instructions that follow.

SECTION 16.0 TROUBLESHOOTING TIPS SteppIR antennas are all powered by stepper motors, hence the name. Stepper motors function by rotating the shaft a specific number of “steps” per revolution. The SDA 100 is simply counting the steps, of which for each step sequence there is a known length that the antenna is adjusting. If for some reason the anten- na gets out of calibration, the method for recalibrating is pretty simple.
Page 94
Again, be careful NOT to short the pins. Even if the controller is turned off, there is always voltage going to the pins with a SteppIR controller. We do this to “lock” the step- per motors, and minimize the need to calibrate the antenna on a regular basis.
